Engineering Survey and Reports
The Engineering Survey and Report (ESR) is prepared each year as required by the California Water Code, Section 60300 et seq. The report determines the past, current, and ensuing year groundwater conditions in the WRD Service Area, including the Central Basin and West Coast Basin. The report contains information on groundwater production, annual and accumulated overdraft, water levels, projects and programs to protect and preserve the groundwater resources, and the quantity, source, and cost of replenishment water anticipated for the ensuing year. The ESR provides the WRD Board of Directors with the necessary information to justify the setting of a replenishment assessment for the ensuing fiscal year (July 1 through June 30) to purchase replenishment water and to fund projects and programs related to groundwater replenishment and groundwater quality over the ensuing water year (October 1 through September 30).
